HAT-PIN.

Application filed March 25, 1913.

To all whom it may concern:

Be it known that I, ALEXANDER B. :KOKER' NOT, a citizen of the United.States, residing at New Orleans, Orleans parish and State of Louisiana,have invented a new and useful Hat-Pin, of which the following is aspecification.

This invention has reference to improvements in hat pins and its objectis to provide a pin of simple construction which may be secured firmlyto the hat and at the same time be susceptible of adjustment lengthwiseof the part attached to the hat.

he present invention which is an improvement upon the hat pin shown inmy application No. 680,209, filed February 27, 1912, for improvements inhat pins, coinprises ahead member of elongated form with means at oneend for attaching it to a hat, and means at the same end for anchoringthe pin after attachment, the said head member being of skeletonconstruction, and to this head member there is applied a shank memberhaving a portion formed to enter the head member and be progressivelymoved therealong in either direction by a screw action, so that theextent of projection of the shank of the pin may be determined at thewill of the operator.

The invention will be best understood from a consideration of thefollowing detailed description, taken in connection with theaccompanying drawings forming a part of this specification, with thefurther understanding that while the drawings show a practical form ofthe invention the latter is not confined to any strict conformity withthe showing of the drawings, but may be changed and modified so long assuch changes and modifications mark no material departure from thesalient features of the invention.

In the drawings :Figure 1 is an elevation of a pin constructed inaccordance with the present invention. Fig. 2 is a perspective view ofthe shank member shown on a somewhat larger scale than Fig. 1. Fig. 3 isa perspective view of the head member with the anchoring means omitted.Fig. at is a perspective view of the anchoring device carried by thehead member. Fig. 5 is a section on the line 55 of Fig. 1, but drawn, ona larger scale. Fig. 6 is a section on the line 66 of Fig. 1 and drawnon the scale of Fig. 5. Fig. 7 is an elevation of a.

portion of the shank member with some parts shown in section.

The pin is provided with a shank l which may be of substantially equaldiameter throughout, except at the two ends, one of which is pointed, asshown at 2, and the other of which is reduced and preferably square, asshown at 3, for the reception of a manipulating button at adapted to thereduced end 3 and there held by a pin 5 or in any other suitable manner.In contradistinction to the point'2 that end provided with the button -lmay be called the butt end and near this butt end the shank 1 haslongitudinal grooves 6 formed therein for the reception of one edge ofeach of a number of fins or webs 7 disposed about the butt portion ofthe shank l in substantially radial relation thereto, and while theinvention is not limited to any particular number of fins or webs 7 itis found that four such fins will answer.

lVound helically about the fins 7 is a strand 8 which may be made ofwire ofa suitable gage, and this strand is secured to the fins bysoldering or otherwise, so as to produce a screw thread of long pitch.In the particular showing of the drawings this screw thread or strand 8has two and onehalf turns, but any particular number of turns is notobligatory and a greater or lesser number of turns may be employed. Thepitch of the thread may be such as to make it quick acting, but not soquick acting that a companion member adapted to the screw thread. willyield to direct forces tending to move it lengthwise of the thread or tomove the thread lengthwise of the companion member.

Admitted to the screw thread 8 is a cage 9 made up of a number of wiresor bars 10 in substantially parallel relation and disposed in circularseries, the drawing showing four such wires, each of a length about thatof the webs or fins 7. At one end of the cage or head 9 the wires 10 areconnected by a ring 11, while at the other end the wires 10 areconnected by a disk 12 which latter has a central passage 13 for the pinshank 1 and at diametrically opposite points at the margins the disk 12carries spurs Meach so bent as to have as the other in helical relationto the longitudinal axis of the disk 12 away from that face of thelatter opposite the face entered a twist in the same direction readilyby the rods 10. The purpose of the spurs 14: is to enter the body of ahat in a manner similar to screw, so as to draw the head member 9'intofirm engagement with the hat by a twisting movement of the head member9. Each wire 10 has notches 15 therein so related one to the other as toreceive the screw thread strand 8, whereby a twisting movement of thepin shank 1- will cause a progressive movement of the shank lengthwiseof the cage or head member 9, and when this head member is to a hat thepin shank may be screwed into or unscrewed therefrom to a limited extentdetermined by the axial length of the head member 9 and of the screwthread strand 8.

Applied to the exterior of the head member or cage 9 is a-sleeve 16having at one end a manipulating iiange 17 which may outstand radiallytherefrom and be suitably formed for the application of the fingers ofthe user, so that this sleeve may be moved longitudinally of the headmember At the other end of the sleeve 16 are axially projecting pins 18the free ends of which may be pointed, and these pins are designed toproject through openings 18* in the disk 12, while a fixed outstandingstud 19 of one of the wires 10 projecting through a longi tudinallyextended slot 20 in the sleeve 16 prevents the said sleeve from rotatingand limits its longitudinal movement, so that the pins 18 when thesleeve is moved in one direction will have their pointed ends withdrawnuntil interior to the outer surface of the disk 12 and when the sleeve16 is moved in the other direction these pins will project beyond theouter surface of the disk 12 to an extent to enter a sufficient distanceinto the wall of the hat. 1f the head or cage 9 be applied to a hat bodyand then twisted so that the spurs 14 enter the hat it will be therebylocked to the hat, but a movement of the head ,member about its axis ina reverse direction would cause the unlocking of the head member fromthe hat and this might quite easily occur. When, however, the sleeve 16is moved so as to cause the pins 18 to enter the hat body after the headmember is locked thereto, then the reverse movement of the head membertending to disconnect the spurs 1d from the hat is prevented, the pins18 acting as anchoring members. Should, however, it be desired todisconnect the pin from the hat it is simply necessary to withdraw thepins 18 by an appropriate sliding movement of the sleeve 16 when thespurs may be readily disconnected from the hat by a reverse movement ofthe head 9.

The efiective length of the shank 1 is determined by unscrewing theshank 1 where extending through the head member 9 to a commensurateextent or screwing it thereinto so far as desired, and the members mayhave a sufficiently snug fit to prevent accidental turning of the shankin the head member 9 when the latter is anchored to the hat.

The head member may be fastened to the hat and left there as long asdesired, while the pin shank 1 may have its pointed end 2 first extendedthrough the head member 9 until it passes through the opening 13, andthen forced through the corresponding portion of the hat body and thehair of the wearer until it engages the other side of the hat body, bywhich time the screw thread 8 has been passed through the ring 11 andinto engagement with the notches 15, whereupon a further progressivemovement of the shank 1 is caused by turning the pin shank, thusscrewing the threaded butt end of the shank into the head member 9 tosuch an extent as to cause the point of the pin to pro ject slightlybeyond the other side of the hat body for engagement with which the pinentirely traverses the hat and pierces the opposite side thereof.

It is sometimes desirable that the threaded butt end of the pin shank besubstantially completely seated in the head member 9 and yet be readilyremovable therefrom, while at the same time not interfering with theready determination of the efiective or active projection of the pinshank 1 from the head member. To bring this about the pin shankindicated at 1 in Fig. 7 may be of substantially even diameterthroughout, except at the two ends, as in the form shown in Fig. 1, butthe grooves 6 are omitted. In place of these grooves there is providedan elongated tube or sleeve 21 which may closely fit the pin shank butnot so closely as to prevent movement of the sleeve lengthwise of thepin shank. On the. exterior of the tube 21 is a helically disposed webor fin 22 designed to replace the fins 7 and the strand 8 and thishelical fin 22 is in efiect a screw thread which may fit the grooves 15and perform the same office as the thread 8. A set screw 23 carried bythe tube 21. provides a means whereby the tube may be socured at anypoint along the pin shank 1 so that even though the tubular member 21with its web screw thread 22 be entirely housed within the head 9 theactive projection of the pin shank 1 will be determined by the locationof the tube 21 on said pin shank, the said tube being fastened in thedesired location by the set screw 23.

The cage or head member 9 and the button the features shown inthedrawing are ample besides producing a simple, cheaply constructed andhighly useful device which may be fixedly secured to a hat withoutinterference with its ready removal, and wherein the effectiveprojection of the pin shank may be readily determined by the user. Thepin shank may be made of maximum length and yet be readily adapted tohats of diflerent sizes, so that there need be no dangerous projectionof the sharp point of the pin beyond that part of the hat body remotefrom the head of the pin.

lVhat is claimed is hat pin comprising a head member having means forsecuring it to the body of a hat, means on the head member and movableindependently thereof and coacting with the securing means for anchoringthe head member to the body of the hat againstthe action of twistingforces, and a shank member, the said head member and shank member havingcoacting screw connect-ions for causing lengthwise movement of the shankmember in the head member, on the turning of said shank member, fordetermining the active projection of the pin shank.
